CAAM-project with intermediate students. This project explores the generation of timebased forms with a 3D-printer. Initial point of the project is the development for a scenography of William Shakespeare's drama 'Twelfth night'. These forms are primarily 'Early forms': this means, that they are generated 'without an author', only by physical forces like gravity, turbulences, nonlinear deformers et cetera. In each act of the drama, the original form is processualy developed futher to a complex spacial system. The idea is, that this process will never be completed. Every condition of this process is tentative and ephemeral. The materialization is realized by the 3D-printing-, 2D-lasercutting- and CNC-5-axis-milling-technology.
